The long-time Bellevue Hill home of the late businessman and property developer Neville Christie sold on Wednesday afternoon for about $22 million.

The result is the highest house sale in the suburb since the neighbouring Leura mansion set a suburb record at $30.8 million in late 2015 when it sold to businessman and yachtie Wilson Lee and his wife Baoyu Wu.

It was owned by the Christie family for the past 56 years after it was sold for £36,500 by merchant James Brown Milne.

Michael and James Dunn, of Richardson & Wrench Double Bay, had a guide of $20 million on the property when it was listed a month ago, and three buyers submitted offers before the expressions of interest deadline on Wednesday.

Michael Dunn declined to reveal the exact sale price or buyer details, confirming only that the property had sold.

Bonnington is set on set on 2200 square metres of north-facing hillside.

According to well-placed sources, one of the underbidders was a senior real estate executive and another is a Point Piper local who heralds from a wealthy Singapore-based family.

The buyer at some $22 million is rumoured to be a senior executive from News Corporation.

The two-storey residence has original period details throughout, including a porte-cochere entry and a grand entry foyer. There are six bedrooms and formal and informal living areas, all set on 2200 square metres of north-facing hillside.
